People also ask, can you use foil tape on a water heater vent?

Furthermore, can I duct tape my exhaust pipe? Duct tape is not a safe option for repairing damaged exhaust mufflers or exhaust pipes.

How hot does water heater vent pipe get?

If a water heater is set to store water at 140 F to minimize Legionella bacteria growth, the flue gas temperature will be about 160 F when the heater is new. As scale builds up and the heater efficiency falls off, the flue gas temperatures can easily increase to over 350 degrees F.
